A waste of $$Do yourself a favor and buy a piece of plastic and cut it yourself. You'll save around $30.
Works as advertised but directions need major editing. Once you get done with the installation you'll be pleased with the performance of the product.
Needs EngineeringThe end product I produced looks as neat and tidy as the pictures you download with this kit.
Despite the many modifications the kit needed, I am happy with the results and my shop is now dust free.

I found a work-aroundI bought 1 of these because quick disconnect is a great idea, especially with my little portable dust collector and I wanted to see if this could work.
I put it on my hose and tried to connect it to my Jet jointer and it just fell right off! I pushed and twisted and it slid off again and again. Tried it on my table saw which has the dust port upside down which will actually help something fall off given the weight of the hose and gravity and it did fall off.
I marched down to a local retailer that sells these and they all did the same thing on their equipment.
Where these did seem to work better was connecting them to blast gates where the seemed matched to each other. They would not reasonably connect to any jointer or tablesaw outlet. I tried a half dozen different combinations.
I wondered how a company can produce something that was a great idea but wouldn't connect to the equipment it was supposed to connect too. I thought I was using the wrong pieces or missing something. The sales people told me that some machines are different and sometimes things just work by trial and errror. That was hardly a reasonable explanation for me. I thought that all the parts from a given brand come from the same mold. I tried cross brands and they were all identical. 2 brands I worked with, Jet and Delta.
So I thought that maybe I should make a pig tail to lay on the ground to plug into. That way gravity won't work against me in either situation.
Before I wanted to waste money making pig-tail 4" hoses I tried one idea. DUCT TAPE.
I hate the idea of duct taping anything other than ducts but i didn't have anything too lose at this point.
Here goes... I wrapped one revolution of silver duct tape around the dust collection outlet of my jointer. This quick disconnect went on beautifully. I was shocked! I think it does 2 things, It obviously increases the friction area to help make a tighter fit and it also is a different material and texture that seems to provide a better grip.
2 hard. slippery plastic surfaces, the dust collector outlets from the machines are slick and tapered naturally making the attaching quick disconnect fitting want to slip slide away from each other. Seems that research and developement should have researched a bit better.
I duct taped the outlet of my tablesaw as well and the fit seems fine. I believe I can enjoy quick disconnect ability now.
Disconnect too easily

Poor Design
PLEASE!If you plan on buying a DJ-20, buy an inexpensive square table saw dust connector (about 1 ft. x 1 ft.), use 1 in. double sided foam tape (like the kind used to hand posters and such), and stick the connector to the side of the DJ-20. You won't be forced to drill any holes in your new expensive jointer, and you'll get a perfect seal around the connector.
Requires modification to router
- Includes two controls with 9V batteries
- This remote switch turns your dust collector on and off from anywhere in your shop up to 75 feet away, saving you trips to your collector whenever you operate a shop machine.
- Use on 220V dust collectors up to 3 HP

Fire HazardSafety issues:
(1) Power cord is 16 gauge, two sizes smaller than the 12 gauge which is the minimum permissible for a 20 amp load. Per my copy of the NEC, this cord is only permissible for up to 13 amps.
(2) Internal switching relay (gizmo which does the turning on and off of the dust collector) is rated at only 1/2 horsepower at 220 volts, not the 3 horsepower advertised for this device. Yes, the relay is also rated at 30 amps, but since the intention of this device is for motor control the 30 amp rating is irrelevant and the horespower rating must be observed.
(3) The circuit breaker with this device is rated at 25 amps, which might in some way help protect against overloading of the relay but would do little to safeguard against overheating of the cord.
(4) No ratings of any kind were marked on the device, nor in the instruction manual.
(5) There was no warning not to use the device to control a different machine, such as an air conditioner, which is far more likely to draw high current for an extended period than a dust collector. This only increases the risk of overheating and fire.
Analysis:
The device came without any warranty, which I find hardly surprising. If you're lucky, it will only self-destruct itself and leave your house alone.
When you consider that an operating dust collector is a large bag of flammable sawdust with a strong breeze blowing through it, you want to be ESPECIALLY careful not to have anything like sparks or small electrical fires nearby.
I would avoid this device, and urge both Amazon and Grizzly to stop offering it, in the interest of public safety. Moreover, I feel existing units should be recalled. With that in mind, I am forwarding a copy of this review along with photographs to the Consumer Products Safety Commission.
BUYER BEWARE & BE INFORMED!

Might Be able to Make it Work

Grizzly: Design Good, Quality Control Poor, Customer Service FairThis made me concerned about the dust collector. My fears were warranted - the box showed up and was beat up. It had some minor crushing and a couple of tears and one good sized hole. The pallet onto which it was stapled had one of the bottom members torn off leaving bare nails sticking out.
The box had an extra piece of cardboard taped to the top which appears to be because the box was so beat up that it needed augmentation. The box looked like it had be opened and taped shut several times. Notice this: Grizzly shipped a 425 lb shipment in a cardboard box stapled to a pallet and it is not bolted down. I'm not an expert in this area, but other manufacturers have sent me such large items crated, bolted down, and with steel bands holding everything in place.
Most troubling, was that inside, the collector parts were haphazardly placed in a somewhat random fashion with pieces of cardboard taped to parts to try and prevent them from damaging one another during shipping.
It didn't work, there was a substantial gouge in the side of the blower housing that was created by a nearby bolt.
Aside from all this packaging/shipping/customer service nonsense, I was impressed with how the unit appeared to be designed. The gauge of the steel was heavy, the welds look good, and the manual is excellent. The finish on the replacement intake barrel was good. The finish on the original was fair to poor (rough surface where air would be flowing).
Update: after all the hassle of replacing the intake barrel I got the machine assembled and running.
I measured the noise level with my meter (keep in mind I have a small shop of about 20x12). It's reading about 87 dbA in operation. Before purchasing, Grizzly claimed it was 83 dbA at one meter (I called and asked, this isn't published). I am satisfied with this 87 dbA at 2 meters. I think it's reasonably close to what they had told me.
The collector worked great - for a week. I then started hearing major squeaking from the motor when shutting down the machine that lasts for nearly a minute! After spending more time disassembling the motor w/ technical service on the line to trouble shoot it, we determined the bearings in the motor are bad.
I'm now an official believer in all the hoopla about buying American motors. It is such a huge pain-in-the-($#((*$# to replace a motor of this size, I'll never mess with a second rate import motor again.
I called back about getting the motor replaced and they told me they can't replace the motor w/o escalating this problem to their home office. The reason, again, being that I hadn't noted the exterior chinks in the packaging on the bill of lading at the time of delivery. In essence, it seemed to me they were saying "if you don't note package damage on the exterior of the box at the time of delivery, your warranty is void". This is despite the fact that I did take digital photos to note it's condition before opening the box and sent them to both Grizzly and Fed-Ex freight. Fed-ex sent out an inspector who seemed to agree with me that both Grizzly and Fed-Ex should take responsibility. As first observer, this looked like more of a problem on Grizzly's end than Fed-Ex.
Update: the home office called stating they would pick up the defective motor, repair it, and send me the repaired motor back out. I found this objectionable because of all the previous hassle and additional downtime and asked that they send me a new motor before requiring me to send the old one back. Now waiting for them to get back to me. This motor is 8 feet in the air and probably weighs over 100lbs. It is a major undertaking to disassemble the dust collector and send it to them. I had to hire two additional guys to install it in the first place because I don't have a fork lift.

- Universal dust hood
- 4 inch OD, 6 1/4 inch length, 6 1/4 inch width

Dust hood would be better without a tapered connection
- 2 inch
- Steel band hose clamp

Not the Preferred Choice of ClampsThe steel band clamp will only strip and never be fully seated trying to compress and secure the wire rib to the smooth DC fitting. The steel banding and worm screw is not designed to do that task and provide the needed pressure to fully seat the ribbed hose. Whereas, the wire clamp will actually strattle the rib on both sides and create a perfect clamping fit.
I tried to save the twenty cents over the wire clamp, and wound up stripping the clamp thread on about 50% of the applications with the steel band clamps. I antied up and spent the extra cash and got the right product, the wire clamps for the ribbed DC hose.

- Ideal for portable power tools
- Adjusts from 24 to 43-1/2 inches
- Nozzle fits any 4" flexible hose attached to a dust collector
- 1-1/8-by-12-1/2-inch wide nozzle rotates 360 degrees
- Can be angled 180 degrees

Absolute Junk AND dangerousGiven the effort level necessary to manufacture this item, somebody is making a big profit on each one sold.
